I would have done a slight ccw rotation to the left and added a little more density using levels. Looks like it might be Garden Island? I don't know Sydney all that well. Good sharpness and nice blue water and sky. The strip of green adds interest. Tfs!

Nice vacation picture Pierre, we get a nice view about these area of the port.
Maybe one advise, I would these picture a little bit turning, these tilt a little bit to the left side.
This makes your composition nice. TFS.
